The major requirements of a high quality conveyor chain are excellent wear life with optimum strength and consistently high fatigue resistance.

In order to achieve such benefits we not only press out and manufacture the various component parts to very close tolerances but first we select high grade steels that, once heat treated, will continue to ensure the desired end results.

We have spent many years working with Scandinavia's leading steel producers refining and honing our steel selections so that we can confidently manufacture high quality conveyor chains for use in the most demanding and arduous applications.

We believe that selecting the correct materials are so important for high quality conveyor chain that we regularly manufacture our chain using 3 different side plate materials. By doing so we can ensure that the resultant conveyor chains will provide optimum performance matched to the required application.

Key to our selection of materials is their weldability.

FB400 - Standard

Similar to St52-3 and S355J2G3 with higher yield strength 410 N/mm²
Carbon content under 0,20%
Hardness circa 180 HB
Very good for welding
Produced in Scandinavia

FB600

Similar to Boron steel 27MnB5
Same material as the pins in FB-conveyor chains
Good for welding
Through hardening to 1050-1200 N/mm2 possible
Produced in Scandinavia

FB800 - This side plate material is often used in applications which require where there is greater wear on side plates area or where extra strength is required.

Similar to StE500 with higher yield strength 520 N/mm²
Carbon content under 0,20%
Hardness circa 220 HB
Very good for welding
Produced in Scandinavia
